IMPROVEMENT IN LAMP-BU RNERS.

The Schedule referred to in these Letters .Patent and making part of the same.

1'0 all whom it may concern: V

- Be itlgnown that I, J osnrn TRENT, of Millerton,

in the county of Dutchess and State of New York,

have invented certain new and useful Improvements in launp iBnrners; and I hereby declare. that the foliowing" is..'a full, clear, and exact description of the same, reference being bad to the accompanying dra'wing which forms part of this specification. My invention consists in a spring forholding the chimney by pressure at two remote "points, and also for holding the hinged cone in a lamp-burner, which spring is constructed of a single piece, and as a. whole is novel and simple, and can be manufactured and appliedmuch cheaper than the separatedevices new 1 employed for the saidtwo purposes; and My invention also consists in the'combination, with a primary and secondary cone in a lamp-burner, of a lamp'chimney whose base is of such form as to constitu-te a third cone, whereby I obtain a high taper flame of great brilliancy.

In the accompanying drawing Figure l is a't-ran'sverse vertical section of my in-v vention taken on the plane of the line x x, fig. 2.

Figure 2 is a plan or top View thereof.

' A designates the base-.plate-of the burner, which i perforated inthe usual manner, and providedwith an upwardly-projecting rim,or with projections. a' a, for retaining in. proper placeacone, B, which latter is hinged to said base plate, as shown at b, and provided with an upwardly-projecting rim or with projections a, a for steadying the chimney. The body (3, with its ratchet-wheel and shaft and wick-tube D, are secured tothe base-plate in the .usual or any suitable manner. .j;

E designates a cone, which I term. a primary cone, to distinguish it from the above-referred to cone 3 which latter'l term a secondaryi'cone.

This primarycone E may be secured in place in any suitable manner-say, by a -cross-bar, (Z, provided with a slot, through which the wick-tube projects and 'the'said, cone is of such height as to rise but a short distance ahovethe wick-tube,; and the slot is cut through its 'apexor 'roundingtop, so as to bc.di-' rectly over the wick-tube so as' to permit the flame to rise in a vertical directionthrough it. As in the operation of my burner there is little'or no lateral expansion of the flame itsform is that of a high thin "column, as will be presently described; and this- ;primary cone is of such diameter as to include, say, two or three rows of perfbrations, and serves to deflect the air received through said perforations more particularly-upon the-top of the [wick-tube, thereby keeping the same 0001, aswell asdeflecting air against the flame at its very base, and hence insuring a suffi cient supply of qirygento the flame at this important point.v j r The secondary cone is provided with a slot for the -flame substantially like that in the primary cone, and this secondary cone includesthe remainder or a greater portion of the perforations, and deflects the air upotr the flame at a point above the primary cone.

- I. thus combine in'a G designates the chimney-holding spring, which is of a novel construction. It consists of a springbar suitably secured to the plate, and bearing against the chimney atv two separate and distinct points.

Ihave shown each end of the spring as preferably provided with a nose or horizontal lip, which lips rest over the flange on the bottom of the chimney, and, in

connection with one or more ears d d, or an equivalent therefor, on the opposite side ofthe burner, keep the chimney securely in place and this spring G is provided with a downwardly-projecting arm, ,g, which is provided with a slot for the base plate. I

This spring G g is stamped out of metalsay, sprin gbrass-in one piece, as will be clearly understood by reference to the drawing. l

. This spring G 9 is particularly applicable to a lamp I I burner now in the market known as the Excelsior Lamp-Burner. single device two very important features in a lamp-burner ;'namely, a spring which holds the chimney by pressure atitwo remote points,

and-aicatch for looking a hinged cone. a p

I designates the chimney I design using with the above-describedburner; ,It is of such' construction that its base "w constitutes a third cone for the burner. Thcflue is of a steeple-shape, and when the .burner,

with its two cones, and the. chimney with its one cone, are all adjusted properly, I producea burner possessing excellent qualities.

I have found that, by comparing it with the Drum- 'inond-light burner, which gives, probably, thernost intense light of any burner in the market, "I pross duce very nearly as brilliant a light by the consumption of three-fifths less oil during the same time;

hence I may say that the burner hereinfldescribefi with the two metal and one glass'con'es, 'will' produce A a lightof a-given biilliancy at'a less consumption of oiithan any other burner in the market; and instead of the broad bat-wing flame which the saidDruim mond burner gives, and which is so'liable to break chimneys, I produce a high taper or candle flame, not at all liable to break chimneys. What I claim as my invention, and desire to secureby Letters Patent, is'- .v 'J 1. The combination, with a lamp burner, of the spring G g, constructed in one piece, and -answering the twofold purpose of holding the chimney-by pressure at two remote points, andalsolocking the hinged cone securely in position, substantially as hereinspecified. .m I

2. The combination, with theprimary and secondary cones E 'B, of the chimney 1, whose basen constitutes a third cone, substantially as and for thepurposes herein specified. v
